Tried creams, antibiotics, even Accutane? Here's why they never worked.

Those aren't normal pimples. They're deep, they sit under the skin for weeks, they hurt before you even touch them. And that's the tell

if it hurts under the skin, the problem was never on the skin. It starts in the gut. When bad bacteria take over, they trigger inflammation that has to go somewhere, so it pushes out through the skin — the same deep spots, every time. That's why every cream and topical failed. They only ever reached the surface.

Kiyss works where acne actually begins.

Mom of a teen daughter - Cystic acne, ~2 years

"My daughter struggled almost 2 years before Skinfora. Her skin improved dramatically — we saw results within 2–3 weeks. She no longer gets the painful cystic acne that used to last a week or more."

Skin starts settling from the inside. Fewer new painful cysts forming.

Redness fading. Existing breakouts shrinking, not spreading.

Week 3

Clearer, calmer skin — and it keeps improving from here.

3 years of cystic acne

"After about 30 days her deep cysts were shrinking, and the redness and whiteheads started clearing too. Her friends noticed before I even said anything. Her teacher asked what she'd changed. Skinfora didn't just clear her skin — she stopped hiding behind her hair and got her confidence back."

Mom of a teen daughter · Cystic acne, ~2 years
···

For almost two years my daughter's jaw and chin were covered in deep, painful cysts — not the kind you cover with concealer, the kind that ache for days before they ever surface. We saw three dermatologists. She did two rounds of antibiotics that worked for a month and then quit working. Accutane was the next thing on the table, and honestly the side effects terrified me.

A friend mentioned the gut connection and I'll admit I rolled my eyes — another supplement. But nothing else had ever touched the root, so we tried Skinfora. The first couple of weeks were quiet, no dramatic change, and I almost gave up. Then around week three the new painful ones just… stopped coming. That was the first real sign something was different.

By the two-month mark the old cysts had faded to marks instead of mountains, and her skin looked calm for the first time in years. She's still taking it and it keeps getting better. The part I didn't expect was her confidence — she stopped angling her face away from the camera. That's the thing I'd pay anything for.

Mom of a teen son · Face & back acne, ~18 months
···

My son is 15 and the breakouts had spread from his face down to his back and shoulders. He's a confident kid everywhere except in his own skin — he started wearing a hoodie all through summer just to cover up. That's a hard thing to watch as a parent and not be able to fix.

We'd done the washes, the spot treatments, a prescription cream that just dried him out and left him peeling. What I liked about Skinfora was that it wasn't one more thing to smear on already-irritated skin. He took the capsules with breakfast and that was it — no routine to nag him about every night.

It wasn't overnight. I'd guess six or seven weeks before I noticed his forehead clearing. But by around three months his back was the thing that genuinely shocked me. He took his shirt off at the pool without thinking twice. He doesn't talk about his skin anymore — which is exactly how it should be for a 15-year-old.

Mom of a younger daughter · Early cystic acne, ~10 months
···

My daughter is only 12 and started getting these deep bumps really early. I didn't want to put a child that young on heavy medication, but watching her cry at the mirror before school wasn't something I could ignore either. I felt stuck between two things I didn't want. I chose Skinfora specifically because it was gentle — no harsh purge, nothing that would make things worse before better. A small surprise: her stomach settled too. She'd been getting aches after certain foods for a while and I hadn't connected it to her skin at all. Around the one-month mark the redness calmed down, and by week eight or so the cystic ones were far fewer and much smaller. I want to be honest — she's not "perfectly clear." But she's happy, she's not hiding, and it's still improving. For a 12-year-old, that's everything.

Frequently Asked Questions

Is this the same as the probiotics my dentist sells? +

It's the same family of protective strains — BLIS K12 and M18 are the clinically studied ones behind most credible oral probiotics. KIYSS foregrounds K12, M18, and L. reuteri together, the three with published data on gums, plaque, and breath, at a CFU count we print on the label instead of hiding in a blend.

Will it feel like just another mint? +

No. A mint masks smell for twenty minutes and does nothing to the bacteria causing it. KIYSS reseeds protective strains that crowd the harmful ones out over time, so the fresh breath comes from the balance shifting — not from covering it up.

I've tried everything for my gums and nothing stuck. Why is this different? +

Because everything you tried was mechanical or masking — brushing, flossing, rinsing all remove or cover bacteria. None of them change which bacteria colonize under the gumline, which is what actually drives the bleeding. KIYSS is built to do that one different job.

Can I take it with my current medications? +

KIYSS is a sugar-free, non-GMO daily lozenge, but anything you add to your routine should be reviewed with your dentist or doctor first — especially with an existing condition or ongoing treatment.

Why haven't I heard about oral probiotics from my dentist? +

Dental training centers on cleaning and repair — scraping, filling, and treating what's already visible. The microbiome side is newer and moves slower into the chair, which is exactly why so many people who "do everything right" are still surprised the balance was the missing piece.

Can I take it alongside dental treatment or a gum-disease diagnosis? +

KIYSS is meant to support healthy gums, not to replace professional care. If you have a diagnosis, recession, or loose teeth, keep seeing your dentist and treat KIYSS as daily support alongside it, after checking with them.

What if it doesn't work for me? +

Then you send it back within 90 days for a full refund. The guarantee exists so putting the idea to the test costs you nothing but the time.
